Derek Jeter, who takes over as Marlins’ CEO and co-owner next week, has quietly fired four members of the team’s baseball operations department, in the wake of dismissing five prominent team employees last week, according to sources.

And Jeter, once again, asked outgoing Marlins president David Samson to fire the employees for him, according to a source.

Jeter asked Samson to dismiss vice president of player development Marc DelPiano, assistant general manager Mike Berger, vice president/player personnel Jeff McAvoy and vice president/pitching development Jim Benedict. All were informed by Samson in recent days.

DelPiano’s dismissal is the most surprising of the group. Owner Jeffrey Loria lured him away from the Pirates before the 2015 season – where he had most recently served as assistant to the general manager - and DelPiano had worked in the past two years to help establish a new culture within the Marlins’ minor league operations.
